1955 Hunter Valley Floods
The Hunter Valley Floods (also known as the Maitland Flood) of 23 February 1955 was a major flood on the Hunter River in New South Wales, Australia. They were one of the most devastating natural disasters in Australia's history. The flood overwhelmed rivers on both sides of the Great Dividing Range, creating an inland sea the size of England and Wales. Worst hit was the inland city of Maitland, which is sited precariously on low-lying land on the Hunter, and which on this occasion was completely inundated by floodwaters. A total of 25 lives were claimed during a week of flooding that washed away 58 homes and damaged 103 beyond repair. In Maitland alone, 2,180 homes were invaded by water. History Background Heavy rain owing to the influence of La Niña had been occurring over the catchment of the Hunter River since October 1954 when, on 23 February 1955, an extremely intense monsoonal depression developed over southern Queensland and north-east New South Wales and moved sou ...

Tropical Cyclone Naming
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same Tropical cyclone basins, basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give Given name, personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government meteorologist Clement Wr ...

Standard Emergency Warning Signal
The Standard Emergency Warning Signal (SEWS) is a warning siren used in Australia to alert the public of danger. The siren is played over radio, television or public address systems in public places to warn of bushfire, flood, cyclone, tsunami, earthquake or terrorist attack. Use The SEWS tone has also been adopted for use in the new Emergency Alert Australia system which sends standard text messages from the phone number 0444 444 444 which has information about a potential emergency, and a phone call to landlines which starts with the SEWS tone with the words "Emergency! Emergency!" followed by a message regarding the threat and a phone number and/or website with more information. The National Alert System has been tested by the Country Fire Service in Kangaroo Island, South Australia and has also been tested by other agencies. Origins The SEWS was developed by the Bureau of Meteorology in the 1970s for tropical cyclone A tropical cyclone is a rapidly rotating sto ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Tropical Cyclone Warning Centre
A Regional Specialized Meteorological Centre (RSMC) is responsible for the distribution of information, advisories, and warnings regarding the specific program they have a part of, agreed by consensus at the World Meteorological Organization as part of the World Weather Watch. Environmental emergency response programme As a result of the poor communications between countries following the Chernobyl disaster in the Spring of 1986, the World Meteorological Organization (WMO) was requested by the International Atomic Energy Agency (IAEA) and other international organizations to arrange for early warning messages about nuclear accidents to be transmitted over the Global Telecommunications System (GTS). In addition some WMO member countries that lacked extensive forecasting capability requested that specialized pollutant transport and dispersion forecasts be provided during these emergencies. As a result, during 1989 Meteo-France (MF), Environment Canada (EC) and the United Kingdom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
